The Civil Air Patrol suspended the search Monday in the Sierra Nevada mountains for a plane with two Santa Rosa residents on board that never arrived at the Petaluma Municipal Airport a week ago.

Brenda Richard, 53, the pilot, and her husband Mark Richard, 54, left the Truckee-Tahoe Airport in Truckee in their blue and white Socata TB-20 Trinidad plane at 4 p.m. April 17. They were due to arrive that evening.

During the six-day search CAP aircrews from California and Nevada conducted visual and photographic searches for more than 60 flight hours over a heavily-wooded andsnow-covered area 18 miles northwest of Truckee.

"We are extremely disappointed in the outcome of this search," CAP Incident Commander Major Shane Terpstra said in a news release Monday morning.

"We always hope for a fast resolution with missing aircraft searches, but rapidly changing weather compounded with fresh snow worked against us this entire search. Our thoughts and prayers are with the family," Terpstra said.

The Richards have four daughters.

More than 117 CAP volunteers, 15 CAP aircraft and 12 CAP vehicles participated in the search.
